Today (14-August-2021) an earthquake with magnitude Mw3,1 took place in Katla volcano. Other earthquakes where smaller in magnitude.
This earthquake activity appears to be normal late summer activity in Katla volcano. There was a minor increase in conductivity in nearby glacier rivers in last few days, that suggests that cauldrons have been emptying their water this summer. This is normal and happens almost every summer due to glacier melt.
Yesterday (11-August-2021) there was a earthquake swarm on Reykjanes ridge. This earthquake swarm was not felt because of distance from the coastline.
Largest earthquake in this swarm had a magnitude of mb4,4 according to EMSC. Information about this earthquake can be found here. The distance from the SIL network made it difficult to know when this earthquake swarm started and stopped.
It is unclear if this part of the activity period that Reykjanes peninsula and Reykjanes ridge is now entering and is going to last for few centuries.
